freqimpact: freqimpact

In daviddoret/GRCRToolkit: GRC Toolkit

Description

freqimpact is a nickname / contraction for the famous equation Frequency x Impact = Risk, with:

• Frequency is the probability function of a discrete variable corresponding to the number of events taking place.

• Impact is the probability function of a continuous variable corresponding to the magnitude or cost of events taking place.

Usage

freqimpact(n, frequency_function, impact_function, output_class = NULL, ...)

Arguments

n	The desired size of the frequency vector.
frequency_function	A frequency function supporting parameter n that returns a vector of integer frequencies of size n.
impact_function	An impact function supporting parameter n that returns a vector of impacts of size n.
output_class	Default: "vector". If output_class = "data.frame", returns a detailed data.frame with columns frequency, impact_list and factor_value.

Value

a vector or data.frame

Examples

freqimpact(
  n = 8,
  frequency_function = function(n) {return(rbinom(n = n, size = 4, prob = .5))},
  impact_function = function(n) { return(rnorm(n = n, mean = 100, sd = 5))},
  output_class = "data.frame")
